The outcomes of M&A transactions can vary greatly depending on the different dynamics of the deal. This research paper investigates the impact of the origin of the target firm (domestic or cross-border M&A) on the acquiring firm’s performance. We analyze 150 M&A deals of acquiring firms operating in the Swedish High Tech Sector, between 06-03-2007 and 06-03-2017. An event study was conducted in order to highlight the abnormal return associated with the M&A announcement. In order to do this, a linear multiple regression analysis is applied to find out what factors that have an impact on the cumulative abnormal return (CAR) around the announcement of the M&A, where we control for variables such as (1) experience of undergoing M&A transactions, (2) relative size between the two firms and (3) market capitalization. This research generates statistically significant and positive abnormal returns for the acquirers’ performing cross-border M&As, while the opposite holds for domestic M&As. Additionally, the variable experience was found having a positive impact on the CAR. While the relative size and market capitalization both influenced CAR negatively, specifically in cross-border M&A.
